Wi-Fi drops out from time to time. Why wireless Wi-Fi disappears and how to fix it

Today it is already impossible to imagine any apartment or office without its own Wi-Fi network. Having a router is no longer a luxury, but commonplace. But every user sooner or later faces a problem when Wi-Fi is turned off on the phone. Why it happens? Is this a technical problem or just carelessness in use? The article will talk about the main types of errors and how to eliminate them.

Problems with connection

In 99% of cases, Wi-Fi connection problems are caused by the following reasons:

  • Incorrect operation of the router.
  • WiFi settings errors.
  • The presence of third-party programs installed on the device.
  • Incorrect phone settings.

Correct diagnosis will help solve the problem. In most cases, you can do it yourself, without resorting to the help of specialists. Slow internet, for example, could indicate that the network is congested because too many devices are connected.

Settings errors

The first thing you should pay attention to is the settings of the Wi-Fi access point itself. You can check the correct operation through the menu of the router, which can be accessed through the browser. To do this, you need to know the username and password of the user, which are either written on the router itself, or, if they have already been changed, you need to find out on your own or reset the settings. Once the menu is accessed, you need to find out the wireless settings, such as:

  • Channel width (set from 5 to 40 MHz).
  • Channel selection (configured automatically, but you can choose yourself).
  • Baud rate (set to the maximum value).
  • Region (may be the cause of the problem, but very rarely, so it is better not to change this item).

Everything is set correctly, but why does the Wi-Fi on the phone turn off? You need to move on to the next item.

Incorrect operation of the router

If using the router settings menu it was not possible to determine why the Wi-Fi is turned off on the phone, you need to check the operation of the router itself.

Indicators will prompt the user for correct operation. Usually there are three or four of them, depending on the model, and they should all be on or flashing:

  • Nutrition. On different models, the color may vary (green, blue, but not red). But it should always be on, not flashing.
  • The system indicator is always blinking.
  • The WAN indicator is an indicator of the presence of an Internet network.
  • WLAN pointer - shows whether the wireless network is running on the router itself.
  • After them are LAN ports, to which a cable for wired Internet is connected. They do not affect the operation of Wi-Fi.

The router also has a power button with which you can restart the device. This trick helps a lot of people.

The presence of third-party programs installed on the device

Viruses are one of the main problems of the Internet. Because of them, Wi-Fi on the phone is periodically turned off. Why does this happen and how to avoid it? If there is a suspicion that the device has been subjected to a virus attack, it is recommended to install one of the many anti-virus programs and run a scan. The program itself will find viruses known to it and eliminate them.

But such security programs are often themselves a problem for Internet access. Therefore, there is no need to constantly keep the antivirus turned on.

Incorrect phone settings

If unlicensed or broken software is installed on the device, then you should not be surprised that Wi-Fi is turned off. For some reason, this problem happens less often on Samsung phones. Perhaps because the manufacturer fully provides devices with high-quality software. But even in this case, the user can accidentally or deliberately change the factory settings. This problem can only be solved by a complete reset to the original settings. With "native" firmware, problems with Wi-Fi are extremely rare, since it is not subject to third-party influences. But in this case, the user will lose all his data, so important information should be saved before resetting.

Wi-Fi connection problems can often be solved on your own. But physical intervention and repair can permanently damage the device. If the available methods failed to determine why the Wi-Fi is turned off on the phone, you should contact the technical support centers.

Bought a laptop, phone or tablet. A portable device is specially selected to access the Internet via Wi-Fi in any accessible place. However, an unforeseen difficulty arises: for some reason, the connection suddenly disappears. What is the reason? Let's figure it out.

Abrupt and sudden disconnection of the wireless network can happen due to several reasons. They are presented below:

  • Wi-Fi coverage can disappear due to the fact that one of the functions of any modern device, be it a laptop, tablet or phone, is to save battery power.
  • An important reason may be the presence of a weak Wi-Fi signal.
  • Another reason is unexpected driver failures, including the driver responsible for the quality of the wireless network.

However, whatever the reasons why Wi-Fi turns off, they are all pretty easy to fix. It is only important to be able to make the necessary settings, or reinstall the driver. In this case, it is best to download the driver from the official website of the manufacturer, otherwise serious problems may arise in the operation of Wi-Fi. Let's talk about problem solving in more detail.

What to do if there is a weak signal or sources of strong interference?

This factor is a fairly common reason for disabling Wi-Fi communications. Needless to say, this coverage is based on radio signals that can be swayed. It is worth saying directly about the signal level that it is not always stable. It is influenced by some factors, of which the most significant is the voltage in the electrical network. A wide variety of electrical devices are involved in creating interference, which can sometimes be so strong that it interferes with the propagation of a Wi-Fi signal.

Even more annoying is the presence of metal objects between the portable device and the router. When the laptop is located at a fairly large distance from the signal propagation point, it may periodically disappear. Therefore Wi-Fi is turned off. As already noted, the signal is not stable.

When a laptop, phone or tablet is located near the router, the fluctuations are imperceptible, and as they move away, they begin to manifest themselves more and more, and as a result, the Wi-Fi connection breaks. Mobile phones or microwave ovens have a particularly negative impact on communications. You can fix the problem by moving the laptop closer to the wireless router.

Problems Caused by Battery Saving

As you know, one of the fundamental functions of any laptop, tablet and phone is battery life, which is achieved through high-quality battery savings. In this regard, the developers have created a special program that allows you to save energy, and which automatically turns off modules that are not used for a long time.

The same applies to the Wi-Fi adapter. It is quite possible that it will automatically turn off when not in use. However, it happens that the program gives certain failures and, as a result of an unstable connection with Wi-Fi, the adapter turns off after a certain period of time, regardless of whether an Internet connection is currently needed or not.

You can solve the described problem by disabling the mentioned option. To do this, you need to pay attention to the battery icon in the lower right corner of the screen. After selecting it, you should go to "Advanced battery recharge options", and then set the optimal recharge plan. It is quite possible to experiment here until the optimal plan is found.

Finally, select the "Edit" icon. The Power Saving Modes window appears. Here you need to set maximum performance both when running on battery and when operating from the network. Thus, the automatic disabling of the Wi-Fi adapter will become inactive. As a result, Wi-Fi will not suddenly disappear.

However, what if all the work is done in the right way, but the Wi-Fi connection is still constantly disconnecting? This means that the operating system itself has power saving settings. Disabling this feature is possible using the "Wireless Network and Sharing Center". All you need is to right-click on the "Wi-Fi" icon. Then you should select the required pop-up sub-item - "Change settings". Here you need to find the shortcut for the wireless connection and right-click on it. In "Properties" select "Network". Then you should go to "Settings" and select "Power Management". Here you should uncheck the box "Permission to turn off the device in order to save electricity".

In this article, I will try to answer a very popular question, which in most cases is even difficult to explain. They often write to me in the comments about some kind of problem with Wi-Fi, I read the question several times, but I can’t understand anything. And I answer the question with a few questions 🙂 in order to understand what the problem is and clarify the necessary information. Let's talk today about the unstable operation of the Internet, when connected via Wi-Fi.

Let's try to figure out what exactly this connection instability is, what could be the problem, and what can be done to solve problems with the wireless network.

There are times when the Internet does not work as it should. For example, you connected the Internet to your computer via a network cable. We bought and installed a wireless router, and began to connect to the Internet via Wi-Fi. And they began to notice that the Internet was somehow not working properly, it was constantly interrupted, the speed was low, etc.

Probably, I will now highlight the problems that can be attributed to the unstable operation of the wireless network. So, it will be easier for us to navigate the problem itself and a possible solution.

  • Frequent disconnections. For example, you connected a smartphone, and after a while, it turns off by itself. Or a laptop, constantly disconnecting and connecting. I saw cases when the connection disappeared for a few seconds, and was immediately restored. This is not always noticeable, but if you have Skype installed, then its connection status is constantly changing. Or a yellow icon appears next to the connection icon. Here is another article on this issue: ““.
  • Low internet connection speed, or speed spikes when connected via Wi-Fi. It may be that, for example, during the day the speed is normal, and in the evening it drops significantly (If connected by cable, the speed is always stable).
  • Unstable Wi-Fi connection. This includes a large number of connection problems. For example, when the device connects to the network from the second or third time. Or, only in a certain place (for example, near the router, I already wrote about this problem ) .
  • When you notice any problems, but, not always. For example, the Internet works fine for several days, and then strange problems with Wi-Fi begin again. Or, as I already wrote, in the morning everything is fine, but in the afternoon the connection is unstable.

This list could go on, but I think you get the point. I would only like to exclude from this list popular problems that have their own characteristics, and about which separate articles have already been written:

  • Error “ ” on computers, or when there is a connection on mobile devices, but .
  • Errors on mobile devices: , and "".

Solving the problem with unstable Wi-Fi

I have some universal solution. And there are no special settings with which you can adjust the stability of work, either. You have to try and find a solution. I will give you some tips that should help you in this difficult matter.

Restart your router and laptop (smartphone, tablet, etc.).

This is the first thing to do. Just unplug your router and plug it back in. Also, restart the device that you are trying to connect to the network, or that is experiencing some problems.

You need to understand what the problem is.

Everything is simple here. We need to find the culprit. This could either be your router or the device itself. (computer, smartphone, etc.). How to do it? Just try to connect other devices to your network (preferably those that run on the same operating system). If the problem persists, then it's most likely the access point. And the problem must be looked for in it.

If another device connects and the Internet works stably, then most likely the problem is in the device itself. (who had difficulty). I'm already confused myself 🙂.

Make sure the internet is working directly.

What does directly mean? This is when it is connected without a router. Network cable directly to the computer. Perhaps there are some problems on the provider's side. And you are already torturing your router and other equipment 🙂.

Change the channel your wireless network is on.

It is necessary! If there is interference on the channel on which your Wi-Fi is working (as wireless, neighbor networks), then a variety of and incomprehensible problems may arise in the operation of your Internet connection, which are even difficult to explain. For information on how to change the channel, read the article. This is probably the most important and effective advice.

Update the software on the router.

Afterword

If nothing works, then write about your problem in the comments. Try to describe the problem in as much detail as possible. Let's figure it out together.

If you have something to add to the article, I will only be grateful. Good luck!

Unstable Internet over Wi-Fi: a few tips to solve the problem updated: April 23, 2014 by: admin

My phone lost Wi-Fi, what should I do?

    This is how I would answer this question about Wi-Fi on the phone.

    I think that in the situation when Wi-Fi (Wi-Fi) disappeared on the phone, here's what you can do. First of all, you need to check well all the settings on the cell phone itself. You may be able to connect it again.

    You didn't write a model phone, it would be easier to advise something, because everything always happens individually, gadgets are different and the reasons can also be different.

    Go to your phone's settings and see if it's turned off automatically.

    Wi-Fi or the wireless connection is disconnected, this happens, especially with smartphones.

    You can try resetting your phone to factory settings. Check if the password for Wi-Fi from the router is entered correctly. Reboot the router that distributes Wi-Fi, this sometimes helps.

    Try to connect from your phone to wi-fi in another accessible place to check what the reason is, it is in the phone or router.

    This happens at my house too. The laptop is in the farthest room near the window, and I use the phone to surf the Internet, being much closer to Wi-Fi, but it still disappears. This is because the Wi-Fi receiver on the phone is much weaker - just a wall as an obstacle and the signal may disappear, so you need to constantly update the connection. I've kind of gotten used to it.

    If Wi-Fi is lost on your phone, then first you should see if the settings in the phone itself have gone astray, then see if there is a signal on another device, if there is, the problem is in the phone. You can also try turning off and on the Wi-Fi router - sometimes it helps!

    It all depends on what you are using. I will explain the reasons with Android. The first most common is simply that your Wi-Fi channel is overloaded. This often happens in the evening when there are many users. To eliminate this reason, you need to install a dual-band router. The second reason is a weakly charged battery and your Wi-Fi has gone into sleep mode. Just charge the battery. The third reason is the change of DNS servers. You will have to go into the settings to close your current network, and then connect to it again.

    This happens to me often, maybe the reason is a weak signal. Then I have to forget / delete my Wi-Fi network on my mobile device and reconnect to it. And then everything works. I rarely reboot my router.

    Although it is possible that the problem is in the phone, for example, the problem appeared after you dropped it. Perhaps something is broken.

    If suddenly Wi-Fi is lost on the phone, then you must first turn the router on and off, if this does not help, then you should change the communication channel on the router, this often helps, you can also reset all the settings of the router and set them again, if the connection is not resumed, you need to check the settings of the phone itself, they may have gone astray.

    Please enter your phone model. In some mobiles, the Wi-Fi antenna is located in the back cover of the device and the lack of a signal can be caused by a violation of the contact group with the back of the phone. Pay attention to the contacts and clean them if they are dirty. You may have hit the gadget, which led to deformation of the back cover and a violation of the tightness of pressing the antenna contacts to the board of the mobile device.

Editorial response

Smartphones can lose mobile network and wi-fi network. In the event of a loss of a cellular operator's network, the reason may be unreliable operation of the network in a certain mode. Basically, operators support 3G network mode, but the signal of such a network is not always reliable. Due to the weak 3G signal in some regions, the network mode changes automatically and in this case, signal loss is inevitable. To set a weaker but stable signal, you need to enter the menu and then select - Menu -> Settings -> Wireless networks -> Mobile network -> Network mode -> "GSM only".

Network loss can also be affected by:

Auto detect function

Some phones do not have auto network detection by default. If one available network disappears, then the connection disappears along with it, and you need to restart the phone. To activate automatic network detection, you need to enable such a function in the settings.

Wrong network connection

If your device allows you to select the network standard (4G/3G/2G), try switching to another standard. To do this, go to the phone settings and select the desired network manually and restart the phone.

SIM card wear

The reason for the loss of the network may be poor contact with the SIM card. You can check the health of the card by inserting the SIM card into another smartphone. “Perhaps you have an old SIM card, or the card failed for one reason or another, maybe you cut it crookedly. The easiest thing to do is to change the map. Sometimes it can help just to pull out and insert the card back, suddenly it is a little decentered. If you changed the card, got a new one, by the way, it's free, and still the problem continues, but on other phones of the same operator in the same place where you are, everything is in order, then it's a mobile device. In this case, you need to contact the service center or change the phone, ”says gadget expert Ilya Korneichuk.

Poor antenna reception

Inside the smartphone are the main elements of the antenna. Over time, they can fail due to oxidation, deformation or lack of springy contacts for connecting the antenna, as well as breaks in the thin antenna cable. If there is a cable break, then you need to contact a cell phone repair service center.

What to do if the smartphone loses wi-fi?

Often the reason for the loss of the network lies precisely in the router. To check its operation, you should find a free access point and connect to it. If the connection is stable, then the problem is in the router.

Settings failure

You need to look at the router settings and check if the DHCP server is enabled. If this feature is disabled, then your device will simply not be able to get an address and connect. In the router settings, enter the "LAN" section and enable DHCP by checking the appropriate box or selecting "Allow".

Router freezing

The smartphone may lose the network due to the banal freezing of the router. This is easy to check by rebooting it. If this does not help, then the problem lies in its firmware. In this case, download the updated version of the software for your access point from the official website and install it.

“As for the loss of the wi-fi network, the problem is most likely in the router. You should reload it. By the way, I strongly recommend installing the latest firmware with the latest security patches on the router. For routers of normal firms, such firmware is regularly released. The router needs to be protected regularly to increase security so that you do not get hacked. Well, of course, you should set a strong password. This is beyond the scope of signal loss. It also happens that the phone and the router are perfectly functional, but they periodically lose each other. In this case, you should turn it on and off - on the phone, the wi-fi network and turn on and off the router itself, ”says Korneichuk.

Software failure

Sometimes a problem with connecting to a wireless network occurs due to a software malfunction after updating it. In this case, you should first try to perform a general data reset. Enter your smartphone settings. In the "Accounts" tab, find the "Backup and Reset" item. It is worth considering that after performing a reset, all data will be deleted, so you must first save it to your computer.
